BIND data lives in /etc/bind. This directory is seeded with the default files from the Debian bind9 package. Additionally, we add a zones subdirectory.
DomTool periodically deposits /etc/bind/named.conf.local, listing all of our hosted DNS zones and their master/slave statuses and configuration. DomTool also populates /etc/bind/zones with zonefiles referenced by /etc/bind/named.conf.local on any master servers.
1. Permissions
/etc/bind/zones must be owned by user bind so that it can modify/create slave zone files.
